提出了数据链路层中基于量子隐形传态的量子选择重传协议.即在量子网络的两个站点进行通信时,发送方通过加入辅助量子比特位,把一系列的量子比特分成m帧.在连续传送m个量子帧后,接收方根据发送方所提供的经典信息,判断自己是否收到正确无误的量子帧.若接收方收到了正确的量子帧, 则用量子信道返回确认帧;若接收方没有收到量子帧或收到错误的量子帧, 则不返回否认帧.发送方在设定的时间内,根据收到的确认帧判断需要重发的量子帧.由于只重发丢失或出错的量子帧,该协议减少了通信过程的传播时延,提高了通信效率.在整个通信过程中,仅用经典信道传送测量信息,从而降低了经典信道的负担.In this paper we study the quantum selective repeat protocol of data link layer based on quantum teleportation. When two sites are communicating in the physical layer, the sender divides a series of qubits intom frames by adding auxiliary qubits. After continuously transmitting m quantum frames, the receiver judges whether he receives the correct quantum frame according to the classical information provided by the sender. If the receiver receives the correct quantum frames, he returns confirmed frames using the quantum channel. If the correct quantum frames are not received, the receiver does not return denial frames. The sender judges quantum frames which he must resend according to the received confirm frames in setting time. Because the sender resends only the quantum frames which are lost or mistaken, this protocol reduces the transmission delay and improves communication efficiency. In the entire course of communications, the classical channel is used only to transmit the survey information, thus its burden is reduced.
